1. An active-matrix display device comprising:

  • pixel circuits arrayed in a matrix;

    signal lines each of which is interconnected with a corresponding column of the matrix-arrayed pixel circuits; and

    a first scanning line, a second scanning line, a third scanning line, and a fourth scanning line which are interconnected with a corresponding row of the matrix-arrayed pixel circuits;

    each of the pixel circuits comprising;

    a first transistor of which a gate terminal is connected with the first scanning line and of which a first electrode terminal is connected with one of the signal lines;

    a first capacitor of which a first end is connected with a second electrode terminal of the first transistor;

    a second capacitor of which a first terminal is connected with the first end or a second end of the first capacitor;

    a second transistor of which a gate terminal is connected with the second end of the first capacitor and of which a first electrode terminal is connected with a first power line;

    a third transistor of which a gate terminal is connected with the second scanning line, a first electrode terminal of the third transistor is connected with the gate terminal of the second transistor, and a second electrode terminal of the third transistor is connected with a second electrode terminal of the second transistor;

    a fourth transistor of which a gate terminal is connected with the third scanning line and of which a first electrode terminal is connected with the second electrode terminal of the second transistor;

    a fifth transistor of which a gate terminal is connected with the fourth scanning line, a first electrode terminal of the fifth transistor is connected with a third power line, and a second electrode terminal of the fifth transistor is connected with the second electrode terminal of the first transistor; and

    a display element connected with both a second electrode terminal of the fourth transistor and a second power line.
